A T-antenna, T-aerial, flat-top antenna, or top-hat antenna is a vertically polarised simple wire radio antenna used in the VLF, LF, MF and shortwave bands. T-antennas are widely used as transmitting antennas for amateur radio stations, long wave and medium wave broadcasting stations. They are also used as receiving antennas for shortwave listening. The antenna consists of one or more horizontal wires suspended between two supporting radio masts or buildings and insulated from them at the ends. A vertical wire is connected to the center of the horizontal wires and hangs down close to the ground, connected to the transmitter or receiver. Combined, the two sections form a 'T' shape, hence the name. The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection. The T-antenna functions as a monopole antenna with capacitive top-loading; other antennas in this category include the inverted-L, umbrella, delta, and triatic antennas. It was invented during the first decades of radio, in the wireless telegraphy era, before 1920.

Miracles You do not have to look for them. They are there, 24 7, beaming like radio waves all around you. Put up the antenna, turn up the volume - snap... crackle... this just in, every person you talk to is a chance to change the world...
You have the antenna attached to the top here, and then you would have a battery pack attached to the bottom here. When an image is taken there's a separate unit called the satellite node, and the images are sent via radio frequency to the satellite node and then the satellite node uses the Iridium Satellite Network to send that image to where you need it.
Radio telescopes on Earth can not see cosmic radio waves at about 33 feet( 10 meters) or longer because of our ionosphere, so there's a whole region of the universe that we simply can not see, but previous ideas of building a radio antenna on the Moon have been very resource intensive and complicated, so we were compelled to come up with something different.
In addition to broadening Ericsson's portfolio of antenna and filter products, the acquisition will bring vital competence for the evolution of advanced radio network products.
Currently, if an antenna is not perfect, you have to live with it, with the losses, we can change that and be flexible, thus gaining more revenue from the satellite.
